Question

Quizplus · Accepted Answer

To calculate the total GRPs, we multiply the rating of each magazine by the number of ads placed in that magazine and then add them all up.

For Newsweek: 25 x 4 = 100 GRPs
For Southern Living: 30 x 4 = 120 GRPs
For Sports Illustrated: 20 x 4 = 80 GRPs
For Golf Digest: 20 x 4 = 80 GRPs
For GQ: We don't know the rating, but we do know that there was 1 ad placed in GQ during June. So let's call the rating for GQ "r" and plug in the values we know:
r x 1 = ? GRPs

To find the rating for GQ, we need to solve for "r." We can do this by dividing both sides of the equation by 1:

r = ? GRPs / 1 ad

We know the total GRPs (400), so we can set up an equation:

100 + 120 + 80 + 80 + (r x 1) = 400

Simplifying:

r = (400 - 100 - 120 - 80 - 80) / 1 
r = 20

Therefore, the rating for GQ is 20.
